Description complète des menacesExpert
As the fourth largest port in Cameroon, Garoua is a major centre of trade in the country. Much of the wooded grassland around Garoua has been lost and degraded since this species was collected over 100 years ago. This is due to agricultural expansion and intensification, increasing demands for firewood, and urban and industrial development. These pressures are all ongoing. More specifically, major threats to this species in the Garoua area are artificial burning of its wooded grassland habitat for grazing management, overgrazing by livestock and cattle trampling, large scale cutting of woodland trees for firewood, and clearing habitat for cultivation of food crops and cotton.

Mesures de conservation recommandéesExpert
No conservation measures or management plan are in place for this species. It is not recorded from any protected areas. Rediscovery of this species in the wild is a priority since it has not been seen in over 100 years. Nothing is known about its current range, density, and regeneration levels; a survey to collect this data is advisable. An assessment of needs can then be made.
